Application filed September 8, 1920. Serial No. 408,976.

To all whom it may concern:

Be it known that I, Generous Posr HER- RICK, a citizen of the United States, residing at New York city, borough of Man Glass or Lenses, of which the following is a specification.

My invention relates to new and useful improvements in tools for applying and tensioning a retaining wire or strand about a glass or lens in orderto secure the glass or lens to a nose-piece of eye-glasses or The invention particularly contemplates the provision of means for applying and tensioning a retaining wire upon an eye-glass or lens in the manner forming the subject matter of United States Letters Patent granted to me on September 23rd, 1919, No. 1,317,131, although it will be understood that the use or application of the appliance is not specifically limited for use in such relation.

The invention consists .in the improvements to be more fully described hereinafter and the novelty of whichwill be particularly pointed out and distinctly claimed. 7

I have fully and clearly illustrated a form of my invention in the accompanying drawing to be taken as a part of this specification, and wherein: v I

Figure 1 is .a view in side elevation, partly in section, of a preferred embodiment of my invention; v

Figure 2 is an enlarged top plan view of certain portions of the appliance shown in Fig. 1;

Figure 3 is a top plan View of the complete device shown in Fig. l.

Referring to the drawing by characters of reference, 1 designates a support for the eye-glass mountingor other device to which the lens or glass is adapted to be connected by a tensioning. wire surrounding the lens or glass and connected to sa d mounting or device. This mounting support preferably consists of a substantial block of rigid material having an opening 2 to receive the cylindrical upper end 3 of a rigid post or standard 4, the lower ,end of which is adapted tobe rigidly connectedto a work benchby anysuita'ble means (not shown), "for example, abench vice. Said mount ng support 1 is adjustable upon said post in order to take different positions thereon,-

for a purpose which is to be presently described. Any suitable" means for accom plishing the adjustment for holding the mounting support in place may be employed, but I prefer to'einploy a set screw 5 threaded through the rear of the element 1, the inner end of said screw being adapted to be seated in one or the other of two spaced seats or sockets 6, 7 ,in said post or standard 1. The mounting support 1 1sv provided with a recess or'slot 8 extending.

longitudinally of the member 1 and 'preferably at right angles to the longitudinal axis of the longitudinal element' hsaidslot being adaptedto receive a guard or nose piece of the particular type of eye glass mounting used, by way of exainple, in the drawing. The slot 8 divides the element 1 into an upper retaining plate 9 anda lower base-portion 10, and in the side edges ofv said plate 9 are inwardly directed slots 'ori 0. The longitudinal axis of these slots 11,

opposite end of the said member from that bearing the set screw 5, fora purposeto be presently described. I

12 designates a supporting member preferably in the form of a bracket, mounted preferably on the said-p0st 4 and rigidly secured thereto by means of a setscrei v 13, or other clamping device, threadedthrough the bracket and engaging j at its inner end, with the said standard' Mounted on the, bracket is a swinging member 14 pivoted on a bolt 15, passing through an opening'in the member-12, and retained by means of a' nut ldthreaded on the lower end'of said bolt; The pivot for Swinging member i P ferably arranged so that the longitudinal axis of, said pivot is on a line extendingthrough the forward edge of the. slot 11 or.11,", which"at the time is beingemployedforjsu-pporting the post of the'ey e-glass or other mounting, I

and preferably asclose aspossible to the'egiit of the hole in the" ,post through which'hole an end of the wire is drawn;- and bent 1 atorally, or kinked inorder to secure the glass to the mounting and retain the tension in the wire, for example, in the arrangement shown and described in my said Letters Patent No. 1,317,131. On the bracket 1-1 is a support 17 for a wire tensioning device to be presently described. The support 17 is preferably in the form of a post having its lower end adjustably seated in an opening 18 in the bracket 14.- to which it is held by a set screw 19 let through the bracket and impinging the lower end of the member 17. The manner described of connecting the support 17 to the bracket provides for adjustment of the former relative to the latter. In the upper end of the support 17 is a transverse opening 20 to receive a tubular member 21 constituting part of the wiretensioning device, and having a longitudinal. bore through which. the wire being applied to the lens or glass passes, The rear end of the member 21 is threaded, as at 22, to receive a threaded socket 23 on one end of an intermediate sleeve 24, in the rear end of which is slidably and rotatably arranged one end 25 of a Wire clamp 26 of any suitable construction. The wire shown at a passes through the bore of the member 21, through the sleeve 24, a bore in the shank 27 of the said wire clamp, and is held against slipping by means of the jaws 28 of the wire clamp which exert their clamping action by means of a clamping screw 29 and wing nut 30 threaded thereon. The end of the member 26 which is slidably disposed within the sleeve 24: is held within the sleeve by means of a shouldered cap 31 threaded onto the sleeve, as at 32, and having in its head an opening 33 through which the shank 27 slidably projects. The inner end of the shank 27 is provided with a head 34 between which and the forward end of the sleeve 2 1, that is, the end toward the sleeve 22, is arranged an expansible compression spring 35 normally exerting its force to thrust the clamp 28 lengthwise of the sleeve 24 away from said cap 31.

The operation of the appliance above described in applying a wire to a lens and lens mounting is as follows:

The wire a is attached to one end of the mounting or other device to be attached to the lens, and is carried around in the form of a loop, and then passed through the securing opening Z2 through the lens mounting. The mounting is then connected to mounting support element 1. Then the glass or lens having a peripheral groove is placed in the loop and the wire into said groove. The end of the wire passed through and emerging from the securing opening in the mounting is passed through the member 22, the sleeve 24: and shank 27 and is secured to the clamp 28, as shown in Figure 1, The clamp 28 is then held by the hand of the operator or otherwise against rotation and the sleeve 24-. is rotated so as to back-off from the screw threaded sleeve 22, which operation serves to compress the spring 35 and place the wire about the lens under tension, so that the lens is strongly and rigidly gripped to its mounting or other support. When the proper tension is obtained, the operator then swings the clamp and its support 17 on the pivot 15 in the direction of the positions shown in dotted lines and the arrows in Figs. 2 and 3 of the drawing for the purpose of kinking or bending the wire a at the point where it emerges from the securing open ing Z) in the lens mounting whereby the tension in the wire about the lens is maintained and the lens is rigidly secured to the mounting. In the particular type of mounting shown in the drawing the side guards and the posts will be what are known as rights and lefts, and I, therefore, provide the adjustablemounting support 1 with two slots 11 and 11 so that one may be used when the lens is to be applied to the left-hand side of the mounting, and the other he used when the lens is to be applied to the right-hand side of the mounting, and the axial adjustment provides for the swinging of the mounting support 1 so as to bring either the right or left post of the lens mounting into proper alignment, as above described, with the axis of the pivot 15 about which the element 1 1 swings. The adjustable feature of the element 17, afforded by the manner of connecting the same to the swinging element 141, provides for the proper vertical and lateral adjustment of the member 22 of the wire clamp and tensioning device relative to the opening through the post of the lens mounting from which the wire emerges.

In, Figs. 2 and 3 of the drawing the support for the lens mounting is shown swung to one of its points of adjustment to bring the post and the mounting in proper align ment with the axis of the pivot 15. It will be understood that when the slot 11" is used to support the post 'of'the lens mounting that the element 1 will be swung so that the slot 1.1 takes the position over the axis of the pivot 15. .lt will be understood that the clamp may be swung on its joint in any direction to properly kink the wire at the point where it emerges from the opening in said post.
